Are relief valves necessary on diesel fire pumps?
Depending on the specific pump, it is not always necessary to have a main relief valve on a system. The NFPA outlines explicit requirements for overspeed shutdowns for “runaway engines” on diesel-driven fire pumps. Additionally, the fire pump industry is progressing to not using main relief valves. As a result, chum pressures and maximum expected static suction pressures must be calculated for each system. Please contact us for further information.
